OSX Catalina 中 cmath 的 Brew clang++ 问题

Question

在 OSX 10.15 中编译源 R 包时，cmath 反复出现问题，如下；

In file included from /usr/local/opt/llvm/bin/../include/c++/v1/complex:245:
/usr/local/opt/llvm/bin/../include/c++/v1/cmath:313:9: error: no member named 'signbit' in the global namespace
using ::signbit;
      ~~^
/usr/local/opt/llvm/bin/../include/c++/v1/cmath:314:9: error: no member named 'fpclassify' in the global namespace
using ::fpclassify;
      ~~^
/usr/local/opt/llvm/bin/../include/c++/v1/cmath:315:9: error: no member named 'isfinite' in the global namespace; did you mean 'finite'?
using ::isfinite;
      ~~^
/usr/local/include/math.h:749:12: note: 'finite' declared here
extern int finite(double)

R 的安装输出显示带有以下参数的 clang++；

clang++ -fopenmp -std=gnu++11 -I"/usr/local/Cellar/r/3.6.2/lib/R/include" -DNDEBUG  -I"/Volumes/Documents/Library/R/3.x/library/BH/include" -I"/Volumes/Documents/Library/R/3.x/library/Rcpp/include" -I/usr/local/opt/gettext/include -I/usr/local/opt/llvm/include  -fPIC  -g -O3 -Wall -pipe -Wno-nonnull -pedantic -std=c++11 -mtune=native -c AlphaProcedure.cpp -o AlphaProcedure.o

我读过几篇具有类似问题的类似帖子，但 none 的解决方法到目前为止在我的系统上有效。我真的很感激对此的任何意见。

我选择了核选项（全新安装 Catalina）并使用 Apple 提供的 llvm 和 Brew 安装了一些必需的应用程序。所有这些都解决了这个问题。 Makevars 中的一个小修复 CPPFLAGS=-I/usr/local/opt/gettext/include -I$(LLVM_LOC)/include -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include
